I am currently using an older 12mp Olympus camera, which I am relatively happy with. I shoot RAW and sometimes wish for a bit more resilience when post-processing, either in highlight recovery or when lifting shadows.

I am wondering if upgrading to LR4 will give me a significant benefit, and if it will be in any way comparable to upgrading to a next-gen 16mp sensor Oly camera (OM-D EPL5) in terms of DR improvement.I realise I won't get any extra pixels that way, but it will be a) a cheaper upgrade right now, and b) cheaper when I do eventually upgrade to a 16mp Olympus, because I will be a 'late adopter'.Who knows, I might be able to buy a lens as well.Thoughts? Am I expecting too much?
